MACHINE 'ron MAKING MATTnEssEs.

Application filed December 16, 1927. Serial No. 240,474.

My invention relates to improvements in garnetting machines and particularly tothe apparatus for feeding into garnetting machines two or more different materials.

The objects of my invention are: y

1. To provide means whereby two or more different kinds of material'can be fed simultaneously to a garnetting machine in separate streams forming a continuous broad layer", one portion of which shall be of one kind of material and another portion of which Vshall be of another kind of material;

2. To provide means whereby a continuous sheet of one kind of material of the full width or the breadth `of the machine can be fed to the garnetting machine with a compar-y atively narrow section of another kind of material intermingled therewith; y

3. To provide la superiory fillerl for mattresses ycomprising a body largely ofV laminated cotton, but having interposed between various layers of thecotton, thin sheets of a combination of kapok and rayon, or of kapok, rayon and cotton in various proportions, or of kapok and other materials, the layers of such mixed materials being adapted to prevent packing, matting and bunching of the cotton and to maintain the resiliencjy7 of the entire filler for indefinitely long periods of time.

I attain lthese objects by the means illustrated in the accompanying drawings, in which,-

Figure 1 is a planvi'ew of my device with the cover removed, being taken on the line, 1 1, of Figure 2; .Y 0

Figure 2 is a vertical section on the line, 2 2, of Figure 1.

In the drawings 1 represents the ordinary garnetting machine which is well known'and in common use Vand hence need not be described. 2 is the feed delivery apron which receives the material to be fed to the `garnetting machine and` carries it to the rolls, 3, of thegarnetting machine, whence itpasses through the machinel in the ordinary way. 15 is the hopper or feed bin ordinarily used with garnetting machines and 16, the feed pipe through` which the cotton to be garnetted is fed into the feed bin, 15. A

6 represents therspiked apron in common use in the feed bin of garnetting machines,

with spikes,- 7, inclined outwardlyk as shawnl and travel. in thedireetion ef thsfitf i' clination, the spiked apron passing over rolls, 9, mounted upon shafts, 8, rotatably mounted in the bin, 15, and connected with suitable drivingmechanism of any kind.

The spike-cleaner or stripper, 4, is mountt ed at the upper end of the spiked apron, 6, Aand parallel therewith upon a shaft, 5, which may be connected with any suitable drivingl mechanism. i c

The parts so far described are all in common use. f

' A division board or shield, 10',has its lower endpivotally mounted upon a rod or shaft, 11, mounted in suitable lugs, 12, secured to the bottom of the bin, 15, and is secured in a substantially vertical position parallelwith the takeup side of the spiked apron, 6; The

shield, 10, may extend to the full height' 0f the spiked apron, 6; or may extend one-third, one-half, three-fourthsor any other proportionate distance upward on the spiked apron.

When it extends lto thev full height of the apron, Vall thel material ofthe bin will be held out of Contact with themiddleportion of the spiked apron, but when desired toal- Vlow a limited amount of cotton tothe Vtaken up by the middle portion, the 'shield may be reduced in length so that some of the cot'- Aton in the bin, 15, will come inlconta'ct with the middle portion of the spiked apron for a small portion of its upward travel. y

` Anv auxiliary'bin or hopper,29, is secured adj acentthe feed vbin or hopper, 15, and with the partition, 18, constitutes a commonwall Aof each bin or hopper. l

' |The bin, 29, maybe of any desired width in feeding bin, but, forv certain materials such as `kapok or a mixture of Vkapok and rayon,

'or kapok,(rayon and cotton, I prefer to have blast'of air is used to 'ffeed thelbins, 15 and lproportion* tofthe width of the principal 29, the upper portion of each, and v31;"re-y i spectively, vis preferably formed with sides,A

ofb

`other material.

agging, jute, or, aloosefabric of'some kind, which will permit the air 'to escape The beams. @faire bis., as, reparieren;

formed on an angle of approximately 45 degrees and has a spiked feed apron, 21, passing around a pair of rollers, 19, mounted upon transverse shafts, 20, whichare secured in suitable bearings in the sides of the bin,

29, with a drive pulley, 23, secured to the upfrom the stripper, 4, it will lie upon the vupper face of the delivery apron, r2, and be carried to the rolls, 3.

f Inthe practical use of my device, I have found that the resiliency of a mattress filler may be greatly improved by embodying therein a mixture of kapok and rayon or of kapok, rayon and cotton to form the middle portion of the sheet as it leaves the garnettingmachine and that when it is desired to form the middle portion of the garnet sheetY from kapok alone or other lmaterials, the apparatus described herein forms a superior lmeans for feeding 4the kapok to` the garnetting machine and Willsecure a more even distribution thereof than any other means heretofore ini use'of which I am aware. In attempting to feed .kapok through the hopper, 15, by dividing same by vertical partitions as has heretofore been done, it is necessary to feed the kapok by hand through an opening in the front of the bin, 15, whichl I have shown closed by the cover plate, 14, and when sofed, it isimpossible to secure an even feed of the kapok upon the apron, 6, and its s ikes,

v 7, because vthe kapok will roll and bunc 1 and bridge, while with the form and inclination of spiked apron shown in the bin, 29, it is f impossible l,for the kapok or other material to'get away from the spiked apron.V

The inclination of the bottom of the hopper, 29, andv of the spiked apron, 21, may e Vvaried to meet the practical requirements of the different kinds of material; and the length and form of the spikes, 22, may be varied as required. y, Y

In lthe operation ofmy device, the bin or hopper, 15, ischarged with cotton through ythe air blast pipe16, and the bin, 29, Vcharged or loaded with kapok, or with kapok and'rayon with kapok, rayon and cotton Aorfsuch `other mixture as may loe.V desired. The machinery is then started and the s iked apron, 6, carries cotton at approximate its outer thirds over to the stripper, 4, W ich ,strip it from thespikes, 7, and throw it down onto the 'delivery' apron, 2, and at the same time the apron 2l, with its spikes, 22, travels upwardly against the lower surface of the kapok or the mixture with which the bin, 29, is charged and carries limited portions thereof over the u per roll, 19, and down to the stripper, 4, which strips it from the spikes, 22, and it falls ap roXimately upon the middle third of the delivery apron, 2. As the material runs through the garnetting machine in straight lines, the sheet ultimately formed as it passes from the garnetting machine has approximately vits middle one-third formed from the material fed into the. hopper, 29, and its outer thirds formed v'from the material fed into'the hopper, 15, asthe sheet istaken olf in. oblique lines under the present practice in such machines, the material comprising ,the middle one-third combines into a distinct layer imposed between two layers of the material fed from the'hop per, 15. Such takeo deviceshaving been 1n common use for many years, are not 1n-v cluded within this application.

It vis obvious that as the material passes Vfrom the garnetting machine, approximately the outerlateral two-.thirds of they sheet as it leaves the garnetting machine, will be` com# posed of the material fed'from'thev hopper,

15, while approXiniatel the middleone-third of it will be compose vof the material fed from the hopper, 29. A

Various modiiications in the siie andpro.- portions ofthe 4various parts ofy my vdevice and the length of .the Shield, may be made without departing from the spiritof my invention. i f Ivclaim: 1. In 'a machine for making mattress fillers, `thecombination of two hoppersy in each of which there is a feeding conveyor for de? livering filler stock at a common, given point, Y

the conveyor in one hopper being provided with a shield for preventing access of the material to a portion of the conveyor corresponding in width and location to the streamV of material fed by the conveyorin the other hopper. p

` 2. In a feeding apparatus for'garnetting machines, the combination of two hoppers in each of which there is a feeding conveyor for delivering material at a given common point, the conveyor in one hopper being provided with ashieldi'for -preventingfaccess of. the material toa given portion of the apron to the end that material fed by the .conveyor or apron in the other hopper` will ,deliver material in such a manner as to fill inthe vacant 'portion and produce a com'pletevlap to be fed tothe garnetting machine.

3. A feedingapparatus for garnetting machines comprising a wide .hopper and a narrow hopper havlng conveyorsv therein arranged to deliver mattress stock to the garnetting machine in adjacent paths in a given,

common plane, the conveyor 1n the wide hopper being provided With a shield for preventing access of stock to the portion of such conveyor opposite to the conveyor in the narrow hopper.

4. A feeding apparatus for garnetting machines comprising a plurality of hoppers each having, a conveyor therein arranged to deliver stock to the garnetting machine in adjacent paths, the conveyor in one of the hop pers being shielded to prevent access of stock to the conveyor therein in the path of the conveyor of another hopper.

In testimony whereof he aHXes his signature.
